Gemstone Spotlight: Rare Pink Diamonds
Pink diamonds are rare and exquisite gemstones that have recently become a highly coveted item, and a must-have for any diamond lover or collector. With the recent closure of Rio Tinto’s Argyle Mine in Western Australia, we thought we’d shed some light on just how special these dazzling beauties are!
What Makes a Pink Diamond Pink?
No-one knows for sure what causes the pink colour. Unlike other diamonds in the fancy colour family, pink diamonds don’t contain the impurities that they derive their colour from.
Various theories have been presented regarding the origin of the diamond’s unique hue. Scientists speculate that the enormous pressure undergone by pink diamonds during formation is a likely cause, though others believe it could be related to a seismic shock that impacted the stone’s molecular structure.
Colour Variations
Not all pink diamonds are created equal! There is great variation in the shade and intensity of each pink diamond, ranging from soft rose-tones to vibrant raspberry-hues. However, due to the fact that pink diamonds are significantly rarer than their white counterparts, even the lighter shades are still highly valuable and sought-after. The most expensive pink diamonds are often of a pure pink colour, as well as those that exhibit a purplish hue.

Pink Diamond Mining
Pink diamonds were first discovered in India’s Kollur Mine, and have since been found in parts of Brazil, Siberia, Russia, South Africa, Canada and Tanzania. While India and Brazil are still known to occasionally produce these rare diamonds, it is Rio Tinto’s Argyle Mine that has been home to the largest quantity of pink diamonds in history.
Responsible for the production of 90 percent of the world's pink diamonds, the Argyle Mine in Western Australia’s Kimberley region recently closed down in late 2020, prompting a significant change in the diamond market. The mine was known to be home to pink diamonds with unmatched vibrancy and depth of colour, with which no other mine in the world could compete.
Naturally, this has resulted in much uncertainty surrounding the future of pink diamond mining, with the value and demand for pink diamonds set to increase even further. Class A has been lucky enough to obtain some limited edition packs prior to the mine’s closure, which are available for purchase in-store!
